“This sale is for a 1980’s Vintage Kawai K1 Digital Synthesizer Keyboard as pictured. This Synth is vintage and used, but was well taken care of. There are no issues that we have found to note, its sounds great and operates as it should. There will be signs of use since it is used and vintage. Flaws will consist of minor marks, scuffs and scratches, but still better than most I’ve seen (pictured). Truly a great entry level vintage synth at a great price. I used a standard Boss Power Supply with this and only had one for use with all other items we test, so it will not be included with this sale.” Click here to visit listing on eBay

“Kawai K1m Desktop Additive Synthesizer.
Some descriptions gleaned from other listings/online sites (cannot vouch for their accuracy): The K1 has 256 digital samples of waveforms, 50 of which are from acoustic instruments. You combine up to four wave shapes to create very new and unique sounds. The K1 is capable of very good acoustic recreation, excellent unique synth sounds or at times, completely noisy walls of complex sound. 16 voice polyphony. There are 3 versions of the K1 – K1 with keyboard, K1r rackmount, and K1m desktop module.” Click here to visit listing on eBay

“Kawai K1R (1988)
Digital synthesizer rackmount module – good condition, a few scratches but nothing major.

NOTE: internal battery seems to need replacing, as the unit won’t save patches – you can restore patches to it via MIDI SysEx very easily and they will work as long as unit is powered, but will need reloading after a power-off. If you can replace the internal battery, though, or find a memory card for it, then it will be fine.

Other than that, the unit is in great working order – I’ve been using it successfully just loading the bank I want onto it each time.” Click here to visit listing on eBay

Kawai K1M

” Rare module version of the super awesome Kawai K1. Save yourself some desk space!
I’ve always thought these guys were kind of like a grittier Korg M1. Great digital sounds with a unique flavor compared to other options.
Plenty of videos on Youtube to hear what it sounds like + more info. All sounds seem to be the untouched factory presets.

A little dusty but works great.
Unit only. No cables and no power adapter. The last picture shows what voltage to track down. ”

I bought this for just one sound, which I was unable to recreate with anything else (I had an original K1 in the late 80s), but I no longer have a use for it. 2 tier stand included if you want it. ” Click here to visit listing on eBay

Used in good condition, never gigged only used in my home studio.

Unit has a very bright backlight LCD display and comes with the original AC Adapter. Included is a photocopy of the rare and hard to find “Sound Making Book” by Bob Maetas.

I will also include a CD-ROM with the Original Manual, Wave List and Hard to find Service Manual (just in case), I will also include my folder of Kawai K1 sound patches in SysEx format.” Click here to visit listing on eBay

Kawai K1 II Project Machine

“The front of the keyboard has received water damage but this did not spread far inside. There is no sound out of the main outputs, but a distorted sound can be heard from the phones output. I suspect the issue is the volume control having water damage and therefore being stuck on 0. This could be an easy fix. The the main board comes from another synth and had an issue where every eighth played note would suffer from digital distortion. There are 2 broken black keys at the top of the keyboard and 1 cigarette burned white key, although the keyboard does not smell of smoke.”

“Really good condition inside and out as can be seen from the pictures, no signs of old age on circuit board, original Sanyo battery has no leaks and caps look good. (Battery may need replacing at some point).

Externally the device has a few minor marks and has two extra holes on the rear panel for wall mounting. Other than that looks good and sounds good.

No original PSU however i will include a 12v 2A PSU that i have used.” Click here to visit listing on eBay
